SEWING-MACHINE.

Specification of Letters Patent.

Patented Dec. 17, 1918.

Application filed January 31, 1916. Serial No. 75,392.

To all whom it may concern Be it known that 1, ROBERT L. LYONS, acitizen of the United States, residing at Waltham, in the county ofMiddlesex and State of Massachusetts, have invented new and usefulImprovements in Sewing-Machines, of which the following is aspecification, reference being had to the accompanying drawings, formingpart thereof.

This invention has reference to improvements in sewing machines andparticularly to sewing machines adapted at a single operation to sew toa piece of material a stay located at one side of said material and abutton located at the other side of said material. The present machinebeing for the general purpose of the machine described in my U. S.Letters Patent, dated November 16, 1915, No. 1,160,423.

The purpose of the present invention is to simplify and improve the stayor stay button holding device in order that, in some classes of work,said stay or stay button may be positively held from independent lateralmovement and may be yieldingly held by means adapted tobe acted upon bythe presser foot to positively hold said stay or stay button frommovement in one direction during the sewing operation and to permit therelease movement of said stay or stay button after its attachment to thematerial.

Other objects of the invention will appear from the followingdescription.

The invention'consists in such novel features of construction andcombination of parts as shall hereinafter be more fully described andpointed out in the claims.

Figure 1, represents a side elevation of the improved machine partsthereof being in section.

Fig. 2, represents a sectional plan view of the sameas taken on line 22Fig. 1, a stay or stay button being shown in its holder.

Fig. 3, represents a sectional enlarged view of parts thereof taken online 3-3 Fig. 2, showing the work after the sewing operation andbeforethe thread is broken or severed.

Fig. 4, represents a similar view showing the work raised by the liftingof the button clamp and the stay about to leave its yielding holdermember.

Fig. 5, represents a cross sectional view of the work approximately asit will appear as on line 55 Fig. 4: after the release of the stay fromits holder member while the main button still is retained by the arms ofthe button clamp.

Similar charactersof reference designate corresponding parts throughout.

The term stay, used herein, is intended to refer t0v a stay button orany rigid or flexible reinforcing device or material adapted to soreinforce or distribute the pulling or cut-' ting action of stitcheswhich attach a button or other article to a piece of material as toreduce the liability of said stitches being pulled through said piece ofmaterial.

Although my new invention is not necessarily restricted in its usethereby, it is to be understood that the invention is particularlyapplicable to button sewing machines having vibratory button clamps orwork holders adapted to effect movement of the work relative to thestitch forming devices during a series of operations of said devices,said machinespreferably having cooperating means to effect the breakageof the thread.

As shown in the drawings the machine herein employed to illustrate thisinvention 6 indicates the bed of a sewing machine hav ing the standard 7furnished with the arm 8 which carries the head or guide member 9 inwhich is slidably mounted the needle bar 10 furnished with the needle11. J ournaled in bearings of the bed 6 is the shaft 12 which, throughany usual and well known mechanism, not shown, is adapted to operate theneedle bar 10 and the looper 13 which latter is positioned as usualrelative to the path in which needle ll'operates.

Shaft 12 has the usual worms 14 and 15 through which the gears 16 and 17 of the button clamp controlling or moving cams 18 and 19 are driven.These cams 18 and 19 have the cam grooves or ways 20 and 21 the walls ofwhich act against the followers 22 and 23 to effect vibration of thearms 24 and 25 which vibration or vibratory movement is transmittedthrough the shafts 26 and 27, journaled in bearings of the machine, andthrough connections usually employed for such purpose, to effectmovement of the button clamp or work holder 28 relative to the needlewhereby a group of stitches may be sewn.

Button clamp Or work holder 28 has the base 29 having secured theretothe cloth plate 30 of novel construction in that this plate 30 has theopening 31, of a size or diameter slightly greater than the distancewhich this portion of the work holder is moved in the vibratory actionof the button clamp, and in the body of this cloth plate 30 above saidopening 31 is the stay receptacle 32 of a. diameter larger than theopening 31 whereby the body of said cloth plate 30 em bracing saidopening 31 constitutes a supporting member for a stay and the wall 33 ofsaid receptacle 32 constitutes a holding device or means which preventsindependent movement of the stay or button received by said receptacle.At the upper surface of the cloth plate is positioned and preferablysecured the spring bearing member 34 which at its free end overlies thereceptacle 32 somewhat and has the semi-circular or other suitablyshaped opening or clearance 35 having the indicator slot 36 extendingradially of said clearance or at least in a direction to permit thisslot 36 to receive a part of a group of stitches.

The button clamp has the button holding arms 37 so mounted. in the usualmanner that they maybe swung upward to facilitate the placing of thework in position for operatiop and the removal of said work after theoperation. The provision herein shown for raising the free ends of saidarms 37 comprises the chain 38 connecting said arms with the lifter arm39 of shaft 40 which latter is journaled in bearings of the machine andmay be operated in any desired manner.

The stay A is usually a button or similar member of a size and shape tobe received by the receptacle 32 within its holding wall 33. This stayor button A usually has two or four holes, as the case may be, and onepurpose of the slot 36 of spring member 34 is to indicate the line onwhich the bar between the holes of the button should extend while thebutton clamp is at rest in order that, during the operation of suchbutton clamp, said holes may at suitable times be brought intoregistry'with the path of the needle. This slot, notch or indicator 36of course is also of assistance in arranging the position of the stay orbutton A relative to the proposed position of the button B which isplaced in the usual manner between the button holding arms 37 of thebutton clamp whereby the holes of said stay andsaid button may be inregistry.

The stay or button A is placed in the receptacle 32 either by liftingthe free end of the spring bracing member 34 and placing the stay A insaid receptacle or by introducing the edge of said stay beneath saidfree edge of said member 34 and then pushing said stay into saidreceptacle after which member 34 will bear against and frictionallyengage the surface of said stay sufliciently at least to retain the samein the position, to which it is adjusted by rotation in said receptacle,to permit the needle to pass through its holes in the sewing operation.

After the placing of the stay A in position the free end of the buttonclamp, arms 37, is raised and the material C, to which the clamp israised tofacilitate the removal of the button B from the arms 37,approximately as shown in Fig. 4, the free end of spring member 34 willbe raised by reason of its engagement with the stay A and this stay Awill of course be raised with the button B to which it is attached. Thework may now be drawn from the machine and the member 34 will thenspring back into place. It is of the work is in the position shown inFig. 4 another stay may be placed in the receptacle 32.

Having thus described my invention I claim as new anddesire to secure byLetters Patent.
